10. Arifureta – From Commonplace to World’s Strongest – Nagumo Hajime
Arifureta is a 13-episode anime released in 2019 that will keep you entertained throughout.
A group of high school students are transported to a parallel world where they are expected to be heroes and save it from destruction.
But while all the students have exceptional skills, Nagumo Hajime is the exception, as he is weak and has low stats.
After being betrayed and abandoned by his companions into a seemingly bottomless dungeon, Nagumo meets a blonde vampire and things start to change.
Instead of focusing on typical fantasy elements such as fighting and saving kingdoms, Arifureta delves into the realms of psychology and romance, making it a unique and captivating isekai experience.
9. The Promised Neverland – Norman
The setup of this anime is both simple and frightening. Humans and demons ended a long war by reaching an agreement known as The Promise.
Under this agreement, humans and demons will not invade each other’s worlds, but demons will be supplied with human flesh as their food source.
That’s why kids are bred in fake orphanages and raised until they are adopted and eventually fed to high-ranking demons.
The story is told from the perspective of three genius MCs children living in one of these orphanages, Emma, Ray, and Norman, as they plan their escape.
But just when they seem to have made it, a surprising twist occurs: Norman sacrifices himself so that his friends can escape, leaving them on their own.
While The Promised Neverland has a great premise, its quality highly decreases as the series goes on. The first season is well-written and good, but the quality drops significantly in the second season.
